This invention relates to windows and more particularly to improvementsin window frames and sash and in the coaction therebetween.

It is among the objects of my invention to provide a window in which thesash may when desired have great freedom of movement relative to eachother and to the window frame but the window will also be weather tightprecluding substantially all movement of air, moisture or otherwisethrough or around the window, its frame and/or between the sash, i. e.,through or around the window as a whole. Another object of my inventionis to provide a window which when one or more of the parts thereof areconstructed of materials which tend to expand and/or contract throughchanges in the seasons, temperature, humidity and the like, will becapable of retaining its desired characteristics of being freelyoperable as well as being weatherproof. A further object is to provide awindow in which the sash may be easily positioned, wholly or partlyopened or closed, and may be positively secured in any desired positionagainst movement, willful or otherwise. A further object is to provide awindow the sash of which may be bodily removed from the frame whereby tofacilitate the washing of the exterior faces of the sash from theinterior side of the window. A further object of my invention'is toprovide a window in which the sash may be easily removed and/or replacedwithout injury to the sash or frame and by the ordinary and normalmanipulation of the working parts of the window. Another object is toprovide a window the manufacture, installation and use of which will beI economical and which is adaptable to practice in a variety ofmaterials or combination of materials as may be chosen either forpurposes of economy or for artistic or architectural eifects.

A further object is to provide a window frame of l such rugged anddurable design and construction as to substantially eliminate the needfor employment of separate lintels thereabove.

A more specific object of my invention is to provide a window frame oneside of which is movable transversely 4of its length whereby to gripand/or release the sides of the sash as may be desired to carry out someor all of the above objects. Another object is to provide a window framehaving a movable part engageable with the sides of the sash and having ayieldable sealing member through which to permit movement of the partsand maintain a weather-tight closure throughout the desired range ofmovement thereof. Another object of my invention is to provide a windowhaving an adjustably movable part of the frame coacting with the sash insuch a manner that the sash may have around the peripheral edges thereofyielding rubber-like sealing members which may be compressed on movementof the frame member in one direction and in which the frame member hassufficient movement to effectively release the compressible sealingmembers.

Other objects and advantages will appear from the following descriptionof a preferred form of my invention reference being had to theaccompanying drawings in which Figure 1 is an elevation of my window insitu in a wall opening; Figure 2 is a horizontal section taken along theline 2-2 of Figure 1; Figure 3 is a vertical section taken along theline 3--3 of Figure 2; Figure 4 is a vertical section taken along theline 4-4 of Figure l; Figure 5 is a fragmentary transverse section takenin the plane of the line 5 5 of Figures 2 and 4 at and above the levelof the window sill; and Figures 6 and I are fragmentary sections similarto Figures 2 and 4 respectively showing provisions for window screens.

To illustrate a preferred embodiment of my invention I have shown inFigure l the window W comprising an upper sash I, a lower sash 2 and aframe 3 set in a wall 4. It will be noted that the window has aconventional hasp 5 and has an operating lever 6 which may liesubstantially flush with the wall surface, see also Figure 2. The handle6 actuates the mechanism which permits the release of the sash forrelative movement and conversely brings about the tight engagement ofthe sash to form a weatherproof and leakproof joint between the sash andthe frame. For the purpose of example and not for any purpose oflimitation I have chosen to illustrate my invention using more or lessconventional wooden sash I and 2 mounted for movement in'and coactionwith a metallic frame 3. Preferably the frame members are formed ofextruded light metal shapes as will more fully appear. I have chosenthese materials for the purpose of illustration and to show theadaptability of my invention to the use of various materials and variouscombinations of materials.

Turning now particularly to Figure 4 the frame 3 of my window maycomprise a head I0 having an upward reenforcing flange II integraltherewith as well asl downward reenforeing flanges I2 and I3 along withan inwardly positioned decorative and reenforcing ange IA,

the latter serving as a plaster ground or guide for the interior trim ofthe wall 4. As mentioned above the head IEB may preferably be formed ofan extruded shape of such material as aluminum or may be rolled steel orother metal as economy and other considerations may dictate. Preferablythe upward flange II is located inwardly of the exterior decorative wallsurface, such as brick, and outwardly of the back-up tile, lath andplaster. The flanges I2 and I3 are preferably spaced to encompass thesash, sealing means and parts of the side frame members presently to bedescribed. The bottom of the frame comprises the sill I5 preferably witha main sloping part I6 against which the bottom of the sash 2 bears, anda conventionally raised inward shelf portion I'I' lying'at-a higherlevel than the outward sloping portion It as shown. Preferably the shelfII has a lip I'Ia facing the sash and extending between the revealflanges 25 and 42 of the sideframe members and has a downwardlyextending return stripor flange lil corresponding to the decorativestrip I/ above.

The head Iii and sill I5 respectively are joined and spaced by sideframe members 2 and 4U of cross sectional form which I prefer to besubstantially as shownin Figure 2. One of the side frame members 2li,leftwardly as viewed in Figures 1 and 2 is preferably of `a unita-ryextruded shape fixedly related to the head and sill. The side member 4ohoweverhas movable parts and mechanisms presently` to be described byvirtue of which the sash are gripped or released as may be desired. Bothside 'framemembers 2) and 43 in addition to the functions about to bedescribed, may also serve as structural columns resting on the sill andsupporting the head of the frame. Preferably the side members are weldedor otherwise xedly secured'to the head and sill on full bearing areascorresponding to their full crosssectional shape as shown in Figure 2whereby to give rigidity and strength to the whole frame structure. Thehead and sill-preferably overlie the side members as at Illa and I5a,Figures l and 2.

The side frame member as shown in Figure 2 preferably takes a middlebox-like'form v2i which with the central partition 22. Yconvenientlyforms separate wells for the sash weights 23 and 24 which may thus havefree movement. Appropriate sash weight ropes o-r cables, see 82a, Figure4, may pass over pulleys,- not shown, in the tops of the wells andconnect the weight to the respective sash. A vertical flange 25extending, as do the other parts of the member 25J, the full height ofthe frame lies inwardly at about the mid-portion of the central boxstructure 2l to set off the inner reveal of the window, andterminates-in a decorative trimming flange 2tv corresponding with thetrimming flanges I4 and I8 of the head and sill respectively. Theportion of the member 20 lying toward thefoutsideof 'sash' 2 thatthe"surface 32- serves for the sash I.

As shown in Figure 2 the flange Sil with the guiding rib 33 forms alongitudinally extending chan- 1 nel 35 for the sash I, and the rib 33with the the window includes the stiffening flange 21 Y of the framemember.

l flange 34 forms a similar channel 3S for the sash Itwill beobSerVedthat the rib 33 and flange 34 limit the depth of the channels Se and 36whereby the sash'may be removed therefrom in a direction inwardly of thewindow whenever the sash are moved rightwardly no more than the heightofthe rib 33er the flange 34.

The side frame member 49, see also Figures 2 and 3, comprises a mainchannel portion 4I opening toward the sash and extending the full heightThe member 48 terminates on the inward side of the window in a flange 42vcomplementary to the flange 2d above described and the flange 42, inturn terminates in a decorative trimming flange 43 corresponding to thetrimming flanges I4, I8 and 2t. The member 4E) terminates on the outsideside of the window in an outwardly extending angled flange 44corresponding to the angled flange Y 28 and symmetrically disposed withrelation thereto; the angled flange 44 terminating in a beaded terminus45 having an exterior appearance corresponding to the bead 29, but thebead 45 contains a longitudinally extending groove 45 which receives andpositively grips the outward longitudinal edge 41 of the sealingdiaphragm 4B. I prefer that the channel 46 be extruded in the firstinstance with its opening wide enough to freely receive the edge 41 and,upon receipt thereof in the course of assembly of the parts, that thechannel 45 be closed tightly upon the edge 4l' by forcible and permanentdeformation of the material of the innerwall of the. groove 46.

As shown in Figure 2 the side frame member 4i] does not `of itselfreceive directly or have direct contact with the sash I andv 2, butrather the sash are received in and guided by a separate member 5i?ypreferably of box-like cross-section which is movable rightwardly andleftwardly, as viewed in Figure `2, in telescoping relation within thechannel 4I, having a fairlyv close'and free sliding fit therewith. Themember 5B -extends the full height-of the frame member 4t and has asquared top in a close but free sliding fit or contact with the undersurface of the head I and has its bottom surface area inclined to theinclination of the sloping part I6 of the sill `I5 upon which it standsin smooth sldable engagement.

As shown in Figure 2 the member 50 is similar in its form to the boxportion 2i of the xed frame member 2G, and has sash receiving andguiding channels 5I and 52 which preferably correspond in form and shapeto the channels 35 and 35V respectively of the oppositely disposed framemember 2B. The inward flange 53 with its inclined face correspondings tothe flange 34; and rib 54 corresponding to the rib 33;*-the flange 55corresponding tothe Yflange 3D with aninclined Surfacev 56 correspondingto the surface Y32 and Y a y Ibeaded terminus f 5T corresponding to thebead 3| and symmetrically disposed oppositely thereof. The beadedterminus 51 has an inner groove 58 in which is securely gripped andreceived the whole length of the inner edge 41a of the diaphragm seal 48and is secured therewithin in the same way that the outer edge 41 issecured within the channel 46, that is, in a mechanically secure andsubstantially air tight relation.

The diaphragm member 48 is preferably formed of thin flexible metallicor other fluid impervious flexible and resilient stock of light gagewhereby to facilitate the rightward and leftward movementof the boxmember 50, as viewed in Figure 2. whilst sealing off the elements, airand weather from entrance to the main channel 4| of the member 40 and/orbetween the sliding surfaces of the box 50 and the channel 4|. I havefound for example that sheet stainless steel of about 30 gage or lesswill serve the purposes of this diaphragm seal and is capable ofsubstantially endless ilexing within the requirements of life timeoperation of my window. Such a diaphragm will yield readily within thespace provided for it, and will not be adversely effected by exposure tothe elements throughout a desirably long life.

It will be observed that the sealing member 48 preferably takes the formof a deep U-shaped channel within and behind the angled flanged 44whereby to be substantially inconspicuous either from the interior orexterior of the window and presents substantially no differentappearance to the eye when the window is in use than does the emptycomplementary channel lying behind the angled flange 28 of the member20.

As viewed in Figure 4 it will be seen that the diaphragm member i8 iscut squarely at the top but is cut at the bottom whereby to conform tothe inclination of the sill l5 at least when the diaphragm is in theposition which it assumes when the box member 50 is advanced to itsleftward-most position, as viewed in Figure 2, that is to say, when theedge 41a of the diaphragm has its most leftward movement, the bottomedges of the side legs of the U of the diaphragm may, be substantiallysquare and level while the curving portion of the U of the diaphragmpreferably conforms to a helix whereby to accommodate the slope of thesill l5. Since the leg of the diaphragm terminating in the edge 41a isto have movement with the box member 50, and the opposite leg of thediaphragm is to have no bodily movement rightwardly and leftwardly (butmay have some movement incident to the flexing of the diaphragm) thelower edge of the curved part of the diaphragm will in its helical formtend to rise away from the sill in part when the box element 50 is movedrightwardly. To accommodate the tolerances which are desirable inproduction of these members, having in mind the geometrical relationabove discussed, I prefer to provide a rubber-like sealing member 60,see Figures 2, 4 and 5, which may be of substantially U-shaped form asviewed in Figure 2, and is preferably of angled section as shown inFigure 5, having an upstanding leg 6| secured to the lower edge of thediaphragm '66 and having a somewhat horizontally disposed wiping lip 02lying on and sliding over the sill l5 in wiping and sealing contact,being urged downwardly by the resiliency of the member 60. By the use ofthe rubber-lke seal 60 the lower edge of the diaphragm need not conformprecisely to the desired geometrical requirements and may merely bespaced closely enough to the sill I5 to permit the wiping edge 6'2 ofthe rubber-like seal 60 to have continuous contact with the sill wherebyto exclude all movement of air and weather from between the lower edgeof the diaphragm and the sill l5. The rubber-like sealing member 60 maybe secured to the lower edge of the diaphragm 48 either by cement,vulcanization or otherwise as may be found most practicable. A similarsealing member 10, see Fig. 4, may be attached to the upper edge of thediaphragm and have wiping and sealing contact with the lower adjacentsurface of the head I0 whereby to seal the movable joint between thediaphragm and the head.

Referring to Figure 2 the member 50 preferably comprises two sash weightreceiving wells 8| and 82 separated by a partition 80 carrying pulleys,not shown, over which weight cords such as the card 82a may pass andjoin the sash and weights. The rightward wall 83, as viewed in Figure 2,of the member 50 1ies parallel with the wall of the bottom of thechannel 4| of the frame member 40, and carries a pair of brackets 84 and85 in the lower zone thereof and a similar pair, of which one, 81, isshown in Fig. 3. The several brackets are suitably secured to the wall83 as by rivets or other means. The pairs of brackets in turn carry,preferably rotatable, horizontally extending pins 86 and 88. The pins 86and 88 along with their supporting brackets are preferably respectivelyspaced appropriately away from the top and bottom ends of the member 50,whereby to distribute the forces exerted upon the member 50substantially evenly throughout the length thereof. Two pins so spacedare adequate for small and moderate sized windows. More pins similarlycarried and properly spaced may be provided in larger windows to coactwith appropriate actuating means or cams, presently to be described.Preferably the pins 86 and 88 are restrained from axial movement byproximity of the ends thereof to the walls of the channel 4 Juxtaposedto the pins 86 and 88 respectively are slidable channel members 90 and9| each containing inclined cam surfaces defined by inclined slots 92and 93 formed in the legs of the channels respectively, which slotsreceive the ends of the pins 86 and 88 respectively as shown in Figures2 and 3. The channel members 90 and 9| each have in the base thereof alongitudinally extending slot, such as 04 in the channel member 90- and95 in the channel member SI, through which pins or bolts 06 and 91respectively extend and guide the channels 9| and 80 in their slidingmovement upwardly and downwardly within the channel 4| of the member l0as shown in Figure 2. The bolts 96 and 01 are xedly secured in themember 40 whereby to guide the channels 90 and 9| in their respectivemovements. A rack 98 is secured to the channelv member 90 and anoppositely extending rack 99 is secured to the channel member 9| throughwhich the channels are given equal and opposite upward and downwardmovement under the influence of the pinion |00 which engages both racks.The pinion |00 is mounted upon a pinion shaft |0|; the assembly of thepinion shaft and racks being contained, journaled and supported withinan appropriate housing |02, the latter being secured to the wall of themember 40 in the base of the channel 4| between the sliding channelmembers 90 and 9|. As shown in Figure 2, the pinion shaft |0| extendsthrough the member 40 within an appropriate bearing and sleeve and outtnroughthe wall surfacing where it is engagjedfbyv tleelvever"6".'vAPreferablylaiiiishingplateJ 3fis'""set int'Ot'tHe @trimming-edge4'3i'bf the' member-'lid wherebyto proteotthe Walllsurface fromvfffi'erent andmanipulation" of /the'lever E1- Asviewed in Figure-31;elo'ckw'isefrotaticrrof*V the appreciated thaty theangled-slopeof-gthe'ffslots 92 ands andthe corresponding "edgesfthere'of.-v whichrespectively bearupon"thefpinsl 86 and ataken withthe sizeof the pinion'I'i'iilwill. give any desired mechanical: advantage for moving. the boxmember rightwardly and leftwardlyA asviewed inigure 2, .and the:exertion of substantially any desirable force upon the edges of thesash.

In thisposition of theparts it will be observed-that: the channels engaging the lateraledgesof' the' sash affordampleguidance for the desired movement ofthesash-while offering no substantial resistance-to such movement. movementof' the'member dtoward the memberV position-of either or beth `ofL themthat"involun'v tary-"movement thereoffcan besecurlelyprevented.Infthisfrespect myw-ind'ow offersra sub'sta-"ntiall'y' burglareproof'construction becausefeveniif the? On the-A other ,hand'forciblef' 9 sashwere jimmied from its lower-most position still it would not then becomefreely movable because the resistance afforded by the grip upon the sashof the members 2| and 50 would persist even after a strained initialmovement and even after the hasp 5 or any other such instrumentalitywere broken by a jimmy For like reasons children too small to reach oroperate the operating handle 6 (which handle can, of course, be maderemovable against the contingency of undesired manipulation by largerchildren) will be unable to move the sash from the position that willalford desired ventilation for their sleeping quarters without offeringthe child either the hazard or temptation of falling through the' windowopening.

When the member 50 is moved rightwardly from the position shown inFigure 2, it will be seen that the sash may be readily removed fromeither or both their respective guiding channels for the purpose ofcleaning, replacement 0r repair. Fol` washing it is most convenient tolower the sash I down to substantially the level of the lower sash 2 andthen swing the right ends of both sash, as viewed in Figure 2, inwardly,pivoting the sash loosely and separately in the channels 354 and 36until the outside face of the upper sash is freely accessible forcleaning. Thereafter the upper sash may be allowed to rise under theinfluence of the weights 23 and 8| in and adjacent its guiding channelsv35 and 52, whilst the outer surface of the lower sash is being cleaned.In like manner in the course of new construction the complete frameswill be installed in the building walls and then left sashless untilsuch time as the sash are desired to be installed by mere manipulationof the member 50 and the attachment of the sash to their respective sashweight cords.

The same facility of movement of the member 50 that permits theinsertion and removal of the sash I and 2 also facilitates the insertionand removal of storm sash or screens for association with and removableattachment to the angled flanges 28 and 44 and closing contact with thehead ange I2 and the sill portion I6 of my window frame, `see Figs. 6and 7.. In Figure 6 the member 50 has been moved to substantially itsextreme rightward position, and it may be assumed that the sash I and 2,suspended by their vsupporting cords, have been held inwardly of thewindow frame whereby to permit the insertion of the screen or storm sash|20 through the opening between the edge 3| of the flange 30 and thevedge 51 of the flange 55. The screen or storm sash |20 may have beengiven an inclined upward movement under the suspended window sash I and2 whilst the latter are held inwardly; it being practicable to move andinsert the screen |20 so that its upper edge preferably rst contacts thevunder surface of the head I8 of the frame inwardly of the fiange I2thereof whereby to permit the bottom edge of the sash to clear the stepII as it isA swung leftwardly as viewed in Figure 4, about its top edgeas a center. After the screen |20 has been swung generally into the zoneof the outside reveals behind the angled fianges 28 and 44 and outwardlyof the flanges 30 and 55 it can then be freely moved rightwardly withits right frame member |2| lying more or less within and between thelegs of the diaphragm 48. From this position the left frame member |22of the screen |20 may be moved and swung to the right of the edge 29 ofthe flange 28 to permit the brackets f 10 |23, of which two or three maybe vertically spaced along the edge |22, to be slid over and engage theouter face of the bead 29 whilst the shoulder |24 of the frame member|23 engages the inner face of the bead 29. On the rightward frame memberor edge I2! of the sash |20 I provide movable U-shaped clips |25 whichmay be rotated about the axis i25a from the position shown in Figures 6and '7 to a position where the outer leg |26 of the clip |25 freelyexposes the shouldered face |21 of the frame member I2! to contact withthe inward face of the bead of the angled flange 44. `With the clips |25in their open position the screen |20 may be swung to the position shownin Figure 6 and then a quarter turn of the clips |25 will bring the legs|26 thereof into the position shown in Figure 6 to secure the screen inplace. Meanwhile the bottom edge 30 of the sash |20 may rest upon thesill portion I6 as shown in Figure 7, and the top edge |3| may be spaceddownwardly somewhat from the under surface of the head I0 but will havecontact with the inward face of the ange I2, the rightward face asviewed in Figure '7, which lies in the plane of the outward face of thesash |20 as well as in the plane of the outward faces of the langledflanges 28 and 44, see Fig. 4. After the screen or storm sash |20 is inplace the sash land 2 may be returned to operative relation tothechannels 35, 35, 5| and 52 Where they may again be guided and/or graspedby leftward movement of the member and used without interferencefrom-the screen or storm sash |20 whilst the latter remains in theposition shown in Figures 6 and 'l'. Removal of the screen or storm sash|20 will require merely the reversal of the operations mentioned forinsertion, all of which is preferably done from the interior of the roomor building in which my windowis disposed.

When the movable element 50 is in about the position shown in Figure 6,i. e., in a position of extreme rightward movement into the channel 4|,the pins 86 and 88 will have been moved to the outward ends of theinclined slots 93 and,92 as shown in dotted lines at 86a and 88arespectively. It will be observed that the slots terminate adjacentstraight vertical edges 92a and 93a on the legs of the channels 90 and9|. Further movement of the channels 90 and 9| toward each other asinduced by the racks and pinion will move the channels relative to thepins 86 and 88 whereby to position the pins onthe surfaces 92a and 93abeyond the open ends of the slots 92 and 93 and thereby free the pins 86and 88 from retained engagement with the channels 90 and 9|. In thisfree position the member 50` along with the pins 86 and 88 and theirsupporting brackets may be bodily withdrawn from the channel 4I, exingthe diaphragm 48 in the course of such movement. When the member 50 iswithdrawn from the channel il it may be swung leftwardly and upwardly asviewed in Figure 2, the diaphragm 48 serving as a strap hinge tofacilitate such movement whereby to open the channel `lll for inspectionand/or repair of the channel, rack and pinion mechanism or replacementof the parts thereof. Conversely in the initial assembly of the partsthe order of operations may be reversed; the rack, pinion and channelmechanisms being first inserted and mounted in the channel 4I and thenthe channels 60 and 9| drawn together in their most proximate positionsfor receipt of the pinsf86 and 88 upon the surfaces 92a and 93a.Thereafter movement of the channels n 90 and Si to positions `similar tothatshownfin Figure 3l draws the member 5l! yinwardly ef the `.cl'iannel4I more or -less `as may be desi-red.

In the initial assembly ef the whole freine,` tbe head, sills and headmembers are first secured As shown in Figure-2 the end of the pinionopits erating shaft l 1li preferably has a (square ornencircularshanl;uponvivhioh the hub ofthe lever 35 may be remeyeblyatteehed, ,As abovementioned removability of the lever 16 permits the sash `I and n2 to begripped in anydesired position and left in such position substantiallytamper-proof by removal `of lthe lever 5. The--remoyability of the lever-8 also -playsianother role. V'When the sash are firmly gripped betweenthe members v5i! and 2l the lever Gmay be removed and reset on .s
